If I want to sent texts to someone who switched from an iPhone to any other phone, what do I have to do so that my iPhone doesn't think they are still on iMessage?
Edit: turning off iMessage on the iPhone worked. Deleting it from the registered products list linked to the Apple ID as suggested on an Apple thread didn't work.
